If the installation of your direct vent wall furnace from Empire requires a longer than usual venting system, you can use this kit to stretch the vent to the length required. Providing 54 inches of extra length and including two elbow pieces in case a turn is needed, use of this kit is the most convenient way to finish this specialized vent run. Make sure your high quality Empire wall furnace has a safe and efficient vent to match its level of performance.
